Description
The TacFire AR Build Kit packages the major upper-end components needed to assemble a compact 5.56x45mm NATO AR platform pistol around a user-supplied lower receiver. Centered on a 7.5″ barrel, the kit adds a Mil-Spec upper receiver, a bolt carrier group, and a slim free float handguard, all finished in black for a cohesive build.
Kit Includes:
- 5.56x45mm NATO 7.5″ Barrel – USA Made
- Bolt Carrier Group
- Mil-Spec Upper Receiver – USA Made
- Slim Free Float Handguard
Configured for semi-auto operation on a right-handed AR platform, this kit is built around standard AR dimensions and controls, including a manual thumb safety. The components are selected to drop in without modification, making this an efficient starting point for a short-barreled 5.56 pistol build. A lower receiver is not included and must be supplied separately to complete the firearm.
